Hagisonic StarGazer

Hagisonic StarGazer

The StarGazer™ by Hagisonic is a powerful new localization sensor for indoor robotics. It analyzes the reflected images from emitted infrared light that are beamed off of passive landmarks attached to the ceiling. Each landmarks is encoded with a fixed pattern to determine distance and orientation pattern and with a unique id for localization. The system provides extraordinarily high accuracy in position and heading angle. The StarGazer™ is composed of both an Infrared projector and an image processing unit. The HLD passive reflector landmarks are available in two grid sizes: 3x3 and 4x4. The 3x3 HLD1 set provides 31 unique IDs which are perfect for business small labs and offices and for typical sizes of domestic rooms. The 4x4 HLD2 set provides 4095 unique IDs. The HLD1 and HLD2 reflectors are also available in various grid spacings to optimize the StarGazer system for a given ceiling height.

APPLICATION

The StarGazer™ by Hagisonic is a powerful new localization sensor for indoor robotics.

Features

StarGazer™ module analyzes the image from the emitted infrared beam reflected from a passive landmark with a unique ID.

The module has two main sub-components: infrared projector and an image processing unit.

High resolution and high speed localization of position and heading angle is attained.

The passive reflector landmarks are attached to the ceiling.

There is no need for any synchronization or communication between a robot and a landmarks.

Navigational range is easily expanded simply by adding new landmarks to new ceiling areas.

Zones (e.g. rooms, work areas) are distinguished by different IDs.

StarGazer™ performs automatic measurement and calibration of distance between landmarks and ceiling height.

No battery or power supply is required for the landmarks.

Negligible cost for extension of landmarks is possible.

There are minimum affects from environment such as a lighting and sunshine.

Operates equally well at day or night. No external lighting is needed.
